Had one success before.
Now lots of fails:
One video "out of memory / or website fail" error
Next video:
IPFS Error while uploading
TypeError: Failed to fetch
Using Opera
H264 Videos
Solution?
I think it is the encoding.
I tried uploading with one of my videos that I downloaded from YT instead of the video I uploaded to YT.
Voila!
I know there is another solution using Handbrake but this was easier for me, maybe you too.
